Must be a picture from a flashback scene because his claws aren’t infused with adamantium. If you take a closer look you’ll see indeed that they’re just bone claws. But adamntium or not I wouldn’t want to get close to his claws: Wolverine is still a dangerous beast, and he looks enraged on that pic!

Besides this picture there’s also news that Wolverine 2 is actually a sequel to the X-Men trilogy and not a prequel:

“Where this film sits in the universe of the films is after them all. Jean Grey is gone, most of the X-Men are disbanded or gone, so there’s a tremendous sense of isolation for him.”
